We're dividing 64403107 by 437 
Our goal is to divide 64403107 by 437.

On to step 1:
6 divided by 437 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 437

Moving on to step 2:
437 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 437

On to step 3:
If we divide 644 by 437, we get 1 and a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 437 from 644 to get 207.
Append the next digit (0) from the dividend to 207 and continue with: 2070 / 437

Moving on to step 4:
The number 437 fits into 2070 4 times, leaving a remainder of 322.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1748 from 2070 leaves us with 322.
Bring next digit (3) of the dividend behind the 322 and repeat the process: 3223 / 437

On to step 5:
The number 437 fits into 3223 7 times, leaving a remainder of 164.
Put 7 as the next digit of the answer. 
Result so far: 147.0
The remainder is 164 after subtracting 3059 from 3223.
Fetch the next digit (1) from the dividend, attach it to 164 and continue: 1641 / 437

Step 6:
When dividing 1641 by 437, we get 3 with a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 1473.0
Subtract 1311 from 1641 to get 330.
Bring next digit (0) of the dividend behind the 330 and repeat the process: 3300 / 437

Going ahead to step 7:
3300 divided by 437 is 7 with a remainder of 241.
The next digit of our result is 7. 
Result so far: 14737.0
The remainder is 241 after subtracting 3059 from 3300.
Bring next digit (7) of the dividend behind the 241 and repeat the process: 2417 / 437

On to step 8:
437 can be fit into 2417 5 times, resulting in a remainder of 232.
Put 5 as the next digit of the answer. 
Result so far: 147375.0
Subtract 2185 from 2417 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 9:
When dividing 2320 by 437, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 147375.5
Deduct 2185 from 2320 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
If we divide 1350 by 437, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 147375.53
Deduct 1311 from 1350 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
When dividing 390 by 437, we get 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 147375.53
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 12:
If we divide 3900 by 437, we get 8 and a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 147375.5308
The remainder is 404 after subtracting 3496 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 13:
The number 437 fits into 4040 9 times, leaving a remainder of 107.
Use 9 as the next digit of our solution. 
Result so far: 147375.53089
The remainder is 107 after subtracting 3933 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 14:
1070 divided by 437 is 2 with a remainder of 196.
The next digit of our result is 2. 
Result so far: 147375.530892
Deduct 874 from 1070 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 15:
437 can be fit into 1960 4 times, resulting in a remainder of 212.
The next digit of our result is 4. 
Result so far: 147375.5308924
Subtracting 1748 from 1960 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 16:
When dividing 2120 by 437, we get 4 with a remainder of 372.
The number 4 becomes the next digit in our result. 
Result so far: 147375.53089244
Subtracting 1748 from 2120 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final result is 147375.53089244 with a remainder of 3.72e-07.
